Gulf of Tehuantepec Gale Warning: Strong high pressure ridging building behind a frontal boundary in the Gulf of Mexico will continue to support a gap wind event with gale force winds to 40 kt in the region of the Tehuantepec. These conditions will continue through Sun night, allowing for seas to build up to 14 ft. For more information on this event, see the latest East Pacific High Seas Forecast product. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends off the coast of Colombia near 07N77W to 06N88W to 05N97W. The ITCZ extends from 05N99W to 0 9N114W, then resumes W of a trough near 08N122W to 08N140W. Scattered moderate isolated strong convection is noted off the Colombia coast N of 03N E of 81W, and from 05N to 10N between 82W and 90W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO Please refer to the Special Features section above for details on the Gale Warning for the Gulf of Tehuantepec. Gentle to moderate N to NW winds are off the Baja peninsula and the Gulf of California with seas to 3 ft in the gulf and 3 to 5 ft elsewhere off Baja California. Gale force winds continue in the region of Tehuantepec with seas in the 8 to 12 ft range. Otherwise, light to gentle variable winds are elsewhere across the SW Mexican offshores with seas to 5 ft. For the forecast, gale-force winds will continue across the Gulf of Tehuantepec through Sun night with seas building to 14 ft. A weak cold front will move into the northern Gulf of California and off of Baja California Norte on Sat. Fresh to strong winds can be expected in the northern Gulf on Sat morning with seas to 4 ft. The front will stall and dissipate over Baja California Sur and the southern Gulf of California Sun morning. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR Strong high pressure over the W Atlantic extending to the northern Caribbean continue to support fresh to strong NE to E gap winds across the Papagayo region with seas to 6 ft. Light to gentle variable winds with seas to 6 ft are elsewhere, except for moderate SW winds off the coast of Colombia and Ecuador. For the forecast, fresh to strong NE to E gap winds will pulse across the Papagayo region through the middle of next week with seas building to 9 ft over the weekend. Winds will pulse moderate to fresh across the Gulf of Panama tonight through early next week. Elsewhere, winds should remain tranquil for the next several days. Large NW to N swell from the Gulf of Tehuantepec will impact the Guatemala and El Salvador offshore waters Sat night through Sun night. REMAINDER OF THE AREA A 1010 mb low is near 23N140W. Fresh to strong winds are noted north of the low in latest scatterometer data where seas are in the 8 to 13 ft range. There is no convection associated with the low. This system is expected to move westward into increasingly unfavorable environmental conditions during the next day or so, and development into a subtropical or tropical cyclone is unlikely. This low has a low chance of development in the next 48 hours and 5 days. For the forecast, high pressure building N of the low pressure will continue to support a large area of fresh to strong E winds today. As the low moves west of 140W later today, it will substantially weaken. Winds and seas are expected to diminish this afternoon through tonight. $$ Ramos
